Mangrove restoration is an effort to restore degraded mangrove ecosystems with the aim of increasing environmental sustainability, biodiversity conservation and providing social and economic benefits for the community. This research aims to determine the extent to which mangrove restoration can influence the socio-economic life of the community in Batu Panjang Village, Bengkalis Regency. The research method used is descriptive qualitative by systematically analyzing and processing data based on the results of observations and interviews with farmer groups, village officials and stakeholders in Batu Panjang Village. The results of this research show that restoration activities provide (1) a positive impact on increasing community knowledge and understanding regarding the function and role of mangroves in coastal area conservation efforts, (2) community empowerment has been carried out by forming a farmer group, namely the Jeram Batu Panjang (JBP) group and the STYA group which plays a role from the land clearing stage, to the planting stage, (3) but has not yet provided/shown a significant impact in increasing income which will affect the social and economic conditions of the community in Batu Panjang Village, Rupat District. This is shown by the research results that the income earned by the community from mangrove restoration activities from the land clearing stage to the planting stage is only around IDR 475,000 on average, still far below the Bengkalis Regency Minimum Wage of IDR 3,599,029.72.

This study discusses the creation of the logistics of humanitarian aid distribution model at the time of the flood disaster. This distribution model adapted to the commodities needed relief supplies to meet the needs that are not met, this study also discusses the importance of taking into account the influence of climatic data of rainfall especially in the determination of the distribution channel humanitarian aid logistics. Using the calculation method using linear programming and path analysis, with secondary data such as rainfall, logistics and relief commodities roadmap Prop network. Aceh. Results of this study show that (1) the path Meulaboh-Geumpang-Tangse the safest route bypassed by land transport modes based on the weather data of February 25, 2012 and six days later. (2) The amount of demand and supply of commodities logistics of humanitarian aid for flood evacuees in Tangse also predictable for each period although still found their demand is not met.Keywords: distribution systems, humanitarian logistics, transportation, rainfallAbstrak: Penelitian ini membahas pembuatan model distribusi bantuan logistik kemanusiaan pada saat bencana banjir. Model distribusi ini disesuaikan dengan komoditas barang bantuan yang dibutuhkan guna memenuhi kebutuhan yang tidak terpenuhi, penelitian ini juga membahas tentang pengaruh pentingnya memperhitungkan data iklim khususnya curah hujan dalam penentuan jalur distribusi bantuan logistik kemanusiaan. Dengan menggunakan metode perhitungan menggunakan program linear dan analisis jalur, dengan data sekunder berupa curah hujan, komoditi bantuan logistik dan peta jalan jaringan Prop. Aceh. Hasil Penelitian ini menunjukkan bahwa (1) jalur meulaboh-Geumpang-Tangse merupakan jalur yang paling aman dilewati dengan moda transportasi darat berdasarkan data cuaca pada 25 pebruari 2012 dan enam hari setelahnya. (2) Jumlah Permintaan dan pasokan komoditas barang bantuan logistik kemanusiaan untuk pengungsi banjir di Tangse jug

The objective of this study is to study the effect of gamma ray irradiation (15, 30, 45, and 60 gray (Gy) to determine Lethal Dose 50 (LD50) values, and to obtain new Coleus variances in a relatively short time. The study was conducted in a greenhouse at Cikabayan experimental field, Bogor Agricultural University, Darmaga, Bogor in May to July 2013. Gamma irradiation treatment significantly affected height, number of leaves, and number of nodes. Increasing the dose level of gamma irradiation tend to inhibit plant growth. LD50 for yellow/green, green/brown, variegated green/brown of Coleus blumei, and Coleus amboinicus Lour were 48.66, 65.2, 52.81, and 37.62 Gy respectively. C. amboinicus irradiated at a dose level of 45 Gy had different leaf shapes compared to control. Keywords: Coleus, gamma ray irradiation, LD50 values, ornamental plant, torbangun

Torbangun (Coleus amboinicus Lour) is a tropical plant from the Lamiaceae family. Torbangun leaves have a distinct aroma. Torbangun leaves have been traditionally used as a medicinal plant in North Sumatra, Indonesia. Bataknese lactating women in North Sumatra consumed torbangun leaves after giving birth with beliefs that it could increase their breast milk production (lactagogue), and that the leaves can function as anti-fungal and/or anti-bacterial, analgesic, to reduce blood cholesterol, and clean the human uterus. However, scientific evidence on this traditional herb is limited. This research was conducted to: (1) determine the leaf N, P, K, Ca and Fe in different position along the plant and the leaf age as to diagnose the secondary metabolites content of torbangun leaves, and (2) determine the relationship between N, P, K, Ca and Fe leaf concentrations with their metabolite production. The results of the study showed that: (1) the best leaf position and age to determine of the need of N, P, K, Ca and Fe nutrients are on the 3rd leaf position of 5 months-old plant (2) There was a positive correlation between leaf K concentrations with shoot dry weight, Ca with PAL activity, and Fe with total saponins on the 3rd leaf position of 5 months-old plant.Keywords: Coleus amboinicus Lour, torbangun, nutrient, correlation test, secondary metabolites.
